WILLIAM E. WARNER, OF HOUSTON, TEXAS.

FLOOR SURFACER, CLEANER, AND POLISHER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed December 27, 1909. Serial No. 535,190..

To all whom it may concern:

Be it known that I, l/VILLIAM E. lVAnNnn, citizen of the United States,residing at Houston, in the county of Harris and State of Texas, haveinvented certain new and useful Improvements in Floor Surfacers,Cleaners, and Polishers, of which the following is a specification.

My invention relates to new and useful improvements in a floor surfacer,cleaner and polisher.

The object of the invention is to provide a device of the characterdescribed for surfacing and cleaning floors of wood of every kind, aswell as grinding or polishing those of mosaic, marble or any othercomposition.

Another object resides in the provision of a mechanism for operating aplurality of cutting rollers which may be applied to the surface to besmoothed either simultaneously or separately.

A further feature resides in the provision of cutting rollers surroundedwith resilient cushions which serve as a base for sand paper or someother similar material which is designed to be secured upon saidrollers.

\Vith the above and other objects in view, my invention has particularrelation to certain novel features of construction and operation anexample of which is given in this specification and illustrated in theaccompanying drawings, wherein Figure 1 is a side elevation of mycomplete device. Fig. 2 is a partial plan view thereof. Fig. 3 is asectional side elevation of the device showing the operative mechanismthereof. Fig. 4 is a partial plan view of the gear mechanism. Fig. 5 isa side elevation of the form shown in Fig. 4. Fig. 6 is a plan view ofthe foot pedals for operating the device. Fig. 7 is a perspective viewof the connecting rods which connect the foot pedals to the operativelevers. Fig. 8 is a plan view of the cutting roller. Fig. 9 is a partialsectional end view of the same.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, the numeral1 refers to the supporting frame which comprises two suitable sidemembers which are secured together by suitable cross braces.

Numerals 2 and 3 refer, respectively, to conveying Wheels which aredesigned to support the device and transport the same from place toplace. The wheels 2 are [mounted on a suitable steering device i whichis operated by hand lever 5, and the wheels 3 are rigidly mounted onshaft (3.

Suitably mounted on the frame 1 is a motor 7 which is designed toprovide the motive power for the mechanism.

At both the front and rear ends of the frame 1 transverse abradingrollers 8 and 9 are revolubly mounted. These rollers are not mounted onthe frame proper but are secured, respectively, to levers 10 and 11which are pivoted to the side members 1 as shown in Fig. 1. Theserollers 8 and S) are constructed, preferably, of metal and have aresilient covering 12 of rubber or some similar composition so as toprovide a yieldable base for the sand paper or other cutting surface.They are further provided with a longitudinal depression 13 extendingthe full length of the roller upon one side of which a small roller 14is secured and opposing which is another roller 15 whose cross sectionpresents a cam shaped appearance. These rollers do not project beyondthe surface of the abrading rollers and are so disposed, relative toeach other, that one edge of the sand paper may be inserted between saidrollers 14 and 15 and the body of the paper wrapped around said abradingroller and the other edge also inserted between rollers 14 and 15 andthen by a partial rotation of roller 15 the said edges will be grippedbetween said small rollers and the. paper securely held in place, theroller being held in its proper place by a rack and dog arrangement 16.

Upon the shaft of motor 7 is a gear wheel 17 which meshes with gearwheel 18 which is rigidly mounted on shaft 19 carried by the framework 1. The shaft 19 also carries a drive gear 20 which meshes withdrive chain 21 which in turn meshes with gear wheels 22 and 23 carriedrespectively, by the shafts of the cutting rollers 8 and 9 and drivessaid rollers. This chain is held against sagging by means of an idlerpulley 24.

The abrading rollers 8 and 9 are partially :inclosed by hoods 25 and 26,which surround the upper portions thereof. The outer portions of thesehoods are detachable as is shown in Fig. 3. From the center of thesehoods suction pipes 27 and 28 lead, which unite in a common pipe 29. Atthe upper portion of pipe 29 a suction fan is mounted, from the casingof which a discutting rollers and discharges the sameinto the dustreceptacle and is operated by a suitable driving chain or belt connectedwith the motor 7 as shown in Fig. 1.

For the purpose of elevating and lowering I the abrading rollers I haveprovided levers 33 and 34 the former of which is fulcrumed at the point35 and is secured at its forward end to an inverted U shaped member 36,

Which embraces roller 8 and is secured to either end of the shaftthereof. The lever 34 is fulcrumed at the point 37 and is secured at itsrearward end to the inverted U shaped member 38 which embraces roller 9and is secured to the shaft thereof.

Upon the main supporting frame I have mounted the bearing member 39 uponwhich three foot levers 40, 41 and 42 are pivoted, which in turn arehingedly connected to link 43, stirrup 44 and link 45, respectively. Thelink 43 is also secured to lever 34 near its free end so that by thedepression of the pedal end of lever 40 the free end of lever 34 will beelevated and the cutting roller 9 consequently depressed against thesurface to be cut and when said lever is released the cutting roller 9will be elevated through the operation of spring 46. vBy a depression ofthe pedal end of lever 42 the free end of lever 33 will be elevated andabrading roller 8 depressed against the surface to be out and when saidlever is released the roller 8 will be elevated through the operation ofspring 47. The free ends of levers 33 and 34 overlap and are embraced bythe stirrup 44 so that when the pedal end of lever 41 is depressed thefree ends of levers 33 and 34 are elevated and both abrading rollersdepressed against the surface to be smoothed and with the release oflever 41 springs 46 and 47 operate to elevate the said rollers.

The traction mechanism of my device is shown in Figs. 2 and 3. Uponshaft 19 I have mounted a worm gear 48 disposed to mesh with worm gear49 rigidly mounted on drive shaft 50. This shaft 50 is secured to thesupporting frame by bearings 51 and 52 and carries at its free end abevel gear 53. Slidably mounted upon shaft 6 is a double bevel gear 54which is keyed on said shaft against rotation but which slides on ballbearings as shown in Fig. 5. A hand lever 55 is pivoted to the mainframe and held in any desired position by the ordinary rack and dogarrangement shown in Fig. 3, while the lower end ofsaid lever .55 ishingedly connected to one arm of bell crank 56 the other arm of whichoperates to slide the gear wheel 54 back and forth. It is obvious thatwhen gear 53 occupies the position shown in Fig. 2 the tractionmechanism will be out of gear and the transmission mechanism may bethrown in advance gear or reverse gear by a suitable manipulation of thehand lever 55, 7

It will be observed from the above specifications and the accompanyingdrawings that I have provided a device of the character described havinga plurality of abrading rollers, rotatable in the same direction andhaving a single driving chain.
